UNCW? Am I screwed?

<p>I want to get into a good school down south either in South Carolina or North Carolina. Preferably UNCW, College of Charleston or Clemson
But I screwed up my freshman and most of my sophomore year, bad.
Im in my junior year now and so far I have a 3.9 GPA, I got a 160/240 on my PSAT's.
Im in a community service club (with 40 hours community service) and in FBLA. </p>

<p>Do I have a chance for University of North Carolina at Wilmington?
What can I do to improve my chances?
Also do colleges look at your grades year by year? or just your total GPA?</p>

<p>Thank you so much!</p>
